A Word of Advice: Before you decide to get your breasts enhanced, you need to know this about your posture. If your head is set forward, and you have a hunchback type curve in your upper back, you could be at risk for more headaches, neck pain, upper back pain, carpel tunnel syndrome, and degeneration! The average enhancement weighs approximately 350cc. When the weight of the enhancement is combined with the weight of your head, you are more prone to trigger points for pain and degeneration in your spine. Ultimately, you should consult a chiropractor before you consider a breast enhancement to ensure that you have proper posture. Correcting your posture before receiving your enhancement will increase your chances for a more beautiful enhancement and less problems in the future.
